Tolall whom it may comm-n:

Be it known that l, (HARLECS Arui'si' RADER, a citizen of thc lfnilcdStaics, nod a resident or E1 lnso. in ihc county of El iziso and Stateof 'lcxns. have invcnicd a ncw and Improved Carburetor, of which theioll'owing is n full, clear, and cxaict dcscriplion.

The invention relates to cxplosivc cnginos.
